【摘要】：以实施屋顶绿化的一个三层框架结构房屋和一个五层框架结构房屋为例,并结合其他二层和四层的工程实例,按照房屋总层数不同和增加的绿化荷载的大小,分别对结构进行了整体抗震性能分析。通过对增加绿化荷载前后结构周期、楼层地震剪力、框架柱轴压比以及框架柱和框架梁配筋的变化等比较分析,论证是否需对欲进行屋顶绿化的房屋进行结构整体的抗震验算。
[Abstract]:Taking a three-story frame structure house and a five-story frame structure house for example, and combining with other engineering examples of two and four stories, according to the difference of the total floor number of the building and the size of the increased greening load, The seismic behavior of the whole structure is analyzed respectively. Based on the comparative analysis of the structural cycle before and after the increase of the green load, the seismic shear force of the floor, the axial compression ratio of the frame column and the change of the reinforcement of the frame column and the frame beam, it is proved whether it is necessary to carry out the seismic checking calculation of the whole structure of the building which wants to carry out the roof greening.
